Adding Diesel Exhaust Fluid
The DEF gauge (located in the instrument panel) will display the level of DEF
remaining in the tank.
Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Electronic Vehicle Information Center (EVIC)/Driver Information Display (DID).
NOTE:
• Driving conditions (altitude, vehicle speed, load, etc.) will effect the amount of
DEF that is used in your vehicle.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with an
automatic DEF heating system. This allows the DEF injection system to operate
properly at temperatures below 12°F (-11°C). If your vehicle is not in operation for
an extended period of time with temperatures below 12°F (-11°C), the DEF in the
tank may freeze. If the tank is overfilled and freezes, it could be damaged.
Therefore, do not overfill the DEF tank. Extra care should be taken when filling
with portable containers to avoid overfilling. Note the level of the DEF gauge in
your instrument cluster. On pickup applications, you may safely add a maximum
of 2 gallons of DEF from portable containers when your DEF gauge is reading ½
full.
DEF Fill Procedure
1. Remove cap from DEF tank (located behind the fuel door on drivers side of the
vehicle).
2. Insert DEF container or fill nozzle into
DEF fill location and fill DEF tank.
